摘要:
This paper describes a robust methodology for inspection of the changing surface texture of road stones as they undergo simulated traffic polishing. Three-dimensional measurements of surface relief are made at five discrete levels of wear, corresponding to five levels of friction. The advantages of measurement in three dimensions are explored, observations are made about the change in surface appearance and the surface is characterised at each stage using a standard areal roughness parameter.
